Overview
Bus Connections and Termination
The H7506 supports connections between single-channel PES and redundant PES H41q/H51q systems through the BV 7040 and BV 7046 data cables.
The terminal provides the following connection features:
- 25-pole Min-D socket: Connects the PES systems through compatible data cables.
- Two 6-pole plug clamps: Provide connection points for the 2-wire bus.
- Two termination switches: Allow activation of the bus terminating resistors at each end of the 2-wire bus.
Meanwhile, correct termination helps control signal reflections on the bus. Technicians can use the built-in switches to configure termination according to the terminal’s position in the bus wiring.
Transmission Distance
The maximum transmission length depends on the conductor cross-section:
- 1200 m: With a wiring cross-section of 0.25 mm2.
- 2400 m: With a wiring cross-section of 0.5 mm2.
The specified loop resistance is 180 Ohm. Therefore, wiring cross-section and loop resistance should be considered when checking the communication cable requirements.
